HOISTING-BUCKET.

Specification of Letters Patent.

Patented Feb. 16. 1915.

Application filed March 6, 1913. Serial No. 752,519.

Y., ffl? rf/10m. it may concern:

lie, it known that I, DANIEL B. YOUNG- nnwo, citizen of the United States, residing at Charlotte, in the county of Eaton und State of Michigan, have invented certain new and useful Improvements in Hoisting- Buckets, of which the following is a specification. y

This invention relates to an improvement in hoisting buckets.

The primary object of the invention is to provide a bucket which is supported by a hoisting mechanism, which may be used to load coal or other material from cars or bunkers into 'vehicles A further object of the invention is to provide a bucket of this character in which the dumping of the load may be accomplished in a convenient manner, the bucket assuming a closed position as soon as the load has been dumped.

Another object' of the invention is to pro- `vide simple means for normally supporting the door sections which constitute the dump- "1g bottom against movement, said mechan-ism acting in conjunction with resilient .neans which closes the door sections as soon is the load has been deposited.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which:

Figure'l is a front elevation; Fig. 2 is en. end elevation; Fig. 3 is a longitudinal if section, the door sections being shown in their open position; Fig. e is a sectional view showing the arrangement of the latch mechanism; Fig. 5 is a detail View of one of the latch releasing members.

Corresponding and like parts are referred i to in the following description and indicated in all the views of the drawings by the eine reference characters.

In the drawings, designates a recepta` cle which is preferably rectangular, consisting; of side wallill and end walls 12. While tl-is receptacle has been illustrated as con s-:ructed of sheet metal, it will be noted that tie same may be formed oi' weed properly reinforced, or any other suitaee material, the mechanism which forms the snbjectmatt of the present invention in no way depending upon the specific construction ci' the receptacle.

The terminals 13 of a yoke or handle amber 14 are secured to the end wells i2.

This handle member supports a shcave block 15 over which the hoisting cable 16 passes.

By this construction, it will be noted thatr the bucket may be handled by any suitable hoisting and conveying mechanism.

A plurality of supporting plates 1'( are secured to the inner face ot' the side ivalls 12 adjacent their lower edges. These plates each hingedly support a door 18, the edges 19 of the doors abutting when they are closed. the doors thereby forming the bottom of the bucket. An angle iron 20 is secured to the face of each of the doors adjacent its free edge, these angle bars reinforw ing the doors and 'forming engaging surfaces for the latch mechanism which will be hereinafter described. Each of the doors is normally maintained closed by a pluralv ity of coiled springs 23. the coiled springs being secured at one end to the upper edge 24- ol the bucket, their lower terminals being secured to the doors 18. It will be noted by this construction that these springs 'will maintain the doors closed when the bucket is unloaded. but that the loud wiii actuate the doors against the tension of the coiled springs.

The extensions 13 of the handle 14 are continued to a point adjacent the center of the bucket. A latch member 26 is secured to each of these extensions, 4said latch members being formed of relatively heavy resilient material. The terminal 27 of the latch member is enlarged and disposed at right angles to the body portion of the member, said terminal engaging the portions 28 of the angle bars which are carried by the doors, securely holding the doors against opening when the bucket is loaded.

A latch releasing member is pivotally supported on each end of the bucket, and consists of a lever 29, the terminal 30 of which Vis provided with a foot 3l. This foot is provided with a cum face B2 which, When the lever is actuated, will force the lower terminal of the member 26 away from the bucket. A stop 33 is arranged on the end of the bucket in the path of the lever 29, the lever normally being maintained in con-- tact with this stop by the coiled spring 3i, one terminal of which is connected to the lever and the other to the bucket. Thus, it will be obvious that the terminal 3i of the lever 29 will be normally maintained out of Contact with the latch member 26.

V is connected to the upper iermnallof the lever 29, said cable passing over a sheave 36 supported in a bracket 37 which is arranged on the handle 14. It will be understood that the latch mechanisns-are duplicated on both sides of the bucket, and the cables are passed 'over sheaves 38 supported by the block 15. A cable 39 is connected to the cable 35, this cable being drawn when it is desired to release the doors. When the bucket has been illed with material and conveyed ito the point where it is to be dumped, the operator pulls the cable 39 which through the cables will vswing the lever 29 on its pivot against the tension of the coiled spring 34. The cam face 32 of the extension v"31 of the lever contacts with the resilient latch member y26, and as the pull on the cable is continued the extension 37 of the latch member will be forced out of contact with the portions 28 of the angle bars 20. As soon` as the latch members 26 on both sides of the bucket are thus released, the weight of the load will open the doors against the tension of the coiled springs 23. When the load has been deposited, and there is nov longer pressure on the doors, the springs 23 wil draw in the doors to their closed position, the angle bars 20 being received by the latch members 26. It will be seen that the springs 34 will return the lever 29 to a position where it will not contact with the latch members 26 as soon as the pull on the cable 39 is released.

The many advantages of a construction of this character will be clearly apparent,

as it will be noted thatl the device provides an efficient conveying receptacle, which may be conveniently dumped, and in which the door sections constituting the closure. are returned to their closed position as soon as the load is deposited. It'will also be seen that the structure may be easily and economically' manufactured, and that the various parts may be readily assembled.`

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a latch mechanism for containers having a body member and a hinged door forming the bottom thereof, a resilient keeper member carried by the body member, a terminal extension formed on the keeper and adapted to normally engage againstl the bottom face of the door, and a releasing means for the keeper, said means including alever pivoted to the body member, and a cam face foot carried by the lever and adapted to be moved thereby to position between the keeper and the body .member for spacing the keeper therefrom and withdrawing the extension from engagement with the door. f

2. A latch mechanism for containers having a body member and a hinged door forining the bottom thereof, said latch mechanism including-V means for locking the door in closed position and means for releasing the door, said first-mentioned means including a resilient keeper carried by the body member, and a terminal extension formed on the keeper and adapted to normally engage against the bottom face of the door, said releasing means including a lever pivoted to the body member, and a wedge-shaped foot member carried by the lever, the inclined face of the foot lever being ada ted to serve as a cam for spacing the foot rom the body member when moved to position between the keeper and the body member, said extension bein withdrawn from engagement with the oor when the keeper is spaced from the body member.

3. A latch mechanism for containers having a body member and a pair of hinged doors forming the bottom thereof, said mechanism including a resilient keeper member secured to the body member, a terminal extension formed in the keeper and arranged to normally engage the vadjacent `terminals of the doors against the bottom faces thereof for holding the doors in closed position, and means for withdrawing the extension from engagement with the doors, said means including a lever'pivoted 'fo the Vbody member and a wedge-shaped foot carried by the lever and movable to position between the keeper and the body member for withdrawing the extension from engagement with the doors.

In testimony whereof I affix my signature in presence of two Witnesses.
